Tack fuse (contour fuse) firing schedule
Use this schedule for Stainless Steel Ribbon Molds, Tempered Glass Ice Plates and Bottle Glass chunks. This schedule rounds the edges and tacks pieces together, but does not full fuse.

You will need to test this schedule in your particular kiln. My kilns range in tack fuse temperature from 1435F to 1450F. Test and adjust accordingly!
